The Bogen Models SCW20 and SCW35 are heavyduty sound columns designed for sound
reinforcement in churches, theaters, auditoriums, and similar installations where
it is necessary to cover a large area with a minimum number of speakers.The sound
column consists of a vertical array of speakers in a specially-designed rectangular
enclosure, and provides a more effective length of throw than conventional speakers,
as well as a highly directional sound dispersion pattern for reduced reflection
from the floor and ceiling of the hall.
The precisely controlled dispersion
pattern of these sound columns makes possible a maximum of uniformity in coverage
of the desired area with minimum sound projected into undesired areas. The sound
columns are constructed of sturdy particle board, acoustically lined and finished
in a simulated oiled walnut.The removable rear panel (for access to the cone speakers)
contains a polarized screwterminal strip and mounting plate for line-matching
transformers.
The sound column shall be a Bogen Model SCW20, or approved
equivalent. It shall contain four 5-inch cone speakers and shall have an input
impedance of 8 ohms. The cabinet shall be sturdily constructed of 3/8-inch particle
board, acoustically lined, and finished in simulated oiled walnut, with a black
grille. The column shall have a (continuous) wattage rating of 20 watts. Maximum
sound pressure level, measured four (4) feet on axis with 1 watt input shall be
100dB. The frequency response shall be from 80 to 14kHz. Dispersion shall be 45°
in the vertical plane and 90° in the horizontal plane. The removable rear panel
shall provide a polarized screw-terminal strip and plate for mounting a linematching
transformer.
Dimensions shall be 7-1/2"W x 20"H x 4-1/2"D; shipping weight
shall be 12 lbs.- Precisely controlled sound projection
- Directional
characteristics reduce feedback
- Uniform sound level throughout area covered
- Clarity and intelligibility for speech reproduction
- Lower power
requirements than conventional speakers
- Fast and simple installation
